Abstract

In photosynthesis light is absorbed by the light-harvesting antenna and within several tens of picoseconds transferred to the photosynthetic reaction center (RC) where an ultrafast charge separation is initiated. Photosynthetic purple bacteria employ a single reaction center. In contrast, in photosynthesis of plants, algae and cyanobacteria, two reaction centers, Photosystem II (PSII) and Photosystem I (PSI), operate in series. PSII uses light to extract electrons from water (to produce oxygen); PSI uses light to reduce NADP + to NADPH. The electron transfer from PSII to PSI is coupled to the build-up of a proton motive force (pmf) that is used to form ATP. NADPH and ATP are required in the Calvin-Benson cycle to produce a reduced sugar. In the following we will discuss photosynthetic charge separation and photosynthetic light-harvesting with an emphasis on the role of quantum mechanics.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Two-dimensional electronic spectroscopy has revealed cross peaks that oscillated in time in light-harvesting complexes.

    “The two-dimensional spectra revealed the presence of cross peaks [41] that oscillated in time [42].”

    From The future of quantum biology (2018) · cites this paper as [42]

  • A large number of studies associated the cross peaks with couplings between exciton states, while their oscillations were assigned to electronic quantum coherence, i.e. coherent superpositions between exciton states.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
